The ignition control unit 56 is for performing the following processing on the data packet given from the merging unit 54 and giving a data packet that can be calculated to the calculation unit 140. The firing control unit 56 refers to the command information of the given data packet and performs the following processing. If the command information is a one-input command, the firing control unit 56
Transfers the data packet as it is to the arithmetic unit 140. When the command information indicates a command of two or more inputs, the data packet is waited until two packets in which the generation number included in the data packet, the destination information, and the command information all match are detected. When the data packets are prepared, the data part of one data packet is added to the other data packet and transferred to the arithmetic part 140.

A data conversion table 70 is provided in the table memory 132. Data conversion table 70
Is for pre-storing the data when the data conversion is performed on the input data packet.

Referring to FIG. 15, operation unit 140 includes a data address generation unit 82, table access circuits 86 and 88, and a multiplexer 90.

The data address generator 82 has two inputs for receiving the right data RD and the left data LD of the data packet, and an output connected to the input of the first table access circuit 86. The data address generator 82
When the command information OPC is a data conversion command, the table memory 13 is read from the input right data and left data.
This is for generating an address for accessing 2 and giving it to the table access circuit 86 and the multiplexer 90. The data address generator 82 is an ALU.
(Arithmetic logic unit) is included.

The table access circuit 86 is for temporarily latching the address given from the data address generator 82 and giving it to the table memory 132 together with the read / write signal R / W.

The table access circuit 88 is for temporarily latching the data read from the corresponding address of the table memory 132 and supplying it to one input of the multiplexer 90.

Multiplexer 90 has one input connected to the output of table access circuit 88, and the other input to which the output of data address generation unit 82 is applied.
The multiplexer 90 determines whether or not the instruction information OPC is a data conversion instruction, and then the table access circuit 88.
Or the output of the data address generator 82 is selectively output as the left data LD.

It should be noted that, in this arithmetic unit 140, the generation number GN
No processing is performed on T, and it is output to the program storage unit 60 as it is.

Referring again to FIG. 14, program storage unit 60 stores a data flow program in advance.
The program storage unit 60 fetches the program based on the destination information of the given data packet, rewrites the instruction information and destination information of the data packet, and the branching unit 62.
To output to.

The branching unit 62 either gives the given data packet to the merging unit 54 again based on the destination information, or transfers it to another peripheral device or the like.

FIG. 16 shows the format of a data packet processed by this data driven type information processing apparatus on a route other than the route from the firing control unit 56 to the arithmetic unit 140. Referring to FIG. 16, the data packet 150 includes a destination information area F1 and a command information area F2.
, Left operand data area F3 and generation number area F4
Including and Destination information area F1 includes, for example, a 6-bit destination node area and a processor number area. The instruction information area F2, the left operand data area F3, and the generation number area F4 have a length of 9 bits, 12 bits, and 24 bits, respectively.

FIG. 17 shows the format of the data packet 152 given from the firing control unit 56 of FIG. 14 to the calculation unit 140. The data packet 152 includes a destination information area F1, a command information area F2, a left operand data area F3a, a right operand data area F3b, and a generation number area F4. The destination information area includes, for example, a 6-bit destination node area and a processor number area. Instruction information area F2, left operand data area F3
a, right operand data area F3b, generation number area F4
Have a length of, for example, 9 bits, 12 bits, 12 bits, and 24 bits, respectively.

FIG. 18 shows an example of the structure of the generation number area F4. Referring to FIG. 18, generation number field F4 includes field number area FD, line number area LN, and pixel number area PX. For example, these areas FD,
LN and PX are 4 bits, 10 bits, and 10 bits long, respectively.

The generation number is an identifier for identifying the data of each data packet input to the data driven type information processing apparatus. For example, when processing image data, the data driven type information processing apparatus is provided with one data packet per pixel and a generation number of 1
It is thrown in one by one.

When the image data is input to the data driven information processing apparatus, it is assumed that the image data is sequentially input pixel by pixel from the upper left corner of the screen to the right. One generation number can be treated as coordinates for one pixel of image data. When the generation number is divided into three areas of fields, lines, and pixels as shown in FIG. 18, the coordinates of image data in a three-dimensional space including the time axis can be shown.

FIG. 19 schematically shows the coordinates of such image data. Referring to FIG. 19, the field (FD)
Is a coordinate corresponding to the time axis, and indicates the position of the pixel on the screen. The line (LN) is related to the Y-axis and indicates in which line of the screen the pixel exists. Pixel (PX) corresponds to the X axis and indicates which pixel on the row the pixel is. By considering the generation number in this way, it is considered that the generation number is suitable for indicating the coordinates of the image data.

Referring to FIGS. 14 and 15, the conventional data driven type information processing apparatus generally operates as follows.
The merging unit 54 merges the data packet from the branching unit 62 and the data packet provided from the outside, and gives the data to the ignition control unit 56. The firing control unit 56 refers to the instruction information of the given data packet, and if the instruction information indicates a one-input instruction, gives the data packet to the arithmetic unit 140 as it is. If the command information of the given data packet is a command of two or more inputs, the firing control unit 56 waits for the data packets until there are two data packets in which the generation number, the destination information, and the command information all match. To do. When two such data packets are prepared, the firing control unit 56 adds the data portion of one packet to the other packet and transfers the data packet of the format shown in FIG. 17 to the arithmetic unit 140.

The operation unit 140 performs an operation according to the instruction information. For example, in the case of an instruction other than the data conversion instruction, the arithmetic unit 140 operates as follows.

Referring to FIG. 15, multiplexer 90
Selects and outputs the output of the data address generator 82 in response to the instruction information OPC. In this case, the table memory 132 is not accessed.

When the instruction information OPC indicates a data conversion instruction, the data address generation unit 82 generates an address for accessing the table memory 132 from the right data and the left data according to a predetermined method, and causes the table access circuit 86 to generate the address. give. The table access circuit 86 latches this address and supplies it to the table memory 132 together with the read / write signal. The table memory 132 is
The data stored in the corresponding address is given to the table access circuit 88. The table access circuit 88 once latches this output and supplies it to one input of the multiplexer 90. The multiplexer 90 selects the output of the table access circuit 88 in response to the instruction information OPC.

Referring again to FIG. 14, the data packet output from operation unit 140 is provided to program storage unit 60. The program storage unit 60 fetches the program based on the destination information of the input data packet and rewrites the instruction information and destination information portions of the data packet. The program storage unit 60 gives this data packet to the branch unit 62.

The branching unit 62 determines the destination of the data packet based on the destination information of the data packet provided, and transfers the data packet to the merging unit 54 or another peripheral device.

By the way, in the processing of image data,
There may be a case where it is necessary to perform calculation of conversion of pixel coordinates, such as moving, enlarging, reducing, or rotating an image. When the generation number is considered to indicate the coordinates of the image data as described above, it is necessary to change the generation number according to the coordinate conversion formula. Conventionally, the generation number has been changed as follows. Even in the conventional device, two methods are conceivable, that is, using an instruction that directly operates on the generation number, and not using such an instruction. First, a conventional method of changing a generation number by using only a data operation instruction without using a generation number operation instruction and a method of using a generation number operation instruction will be sequentially described below.

(1) When No Generation Number Operation Instruction Is Used When a generation number is converted without using the generation number operation instruction in the conventional data driven information processing apparatus, the following method is used. First, the generation number is copied to the data area. Here, in order not to change the data area of the data packet, it is necessary to save the contents of the data area of the data packet in an accumulator or the like in advance.
Subsequently, the generation number copied in the data area is changed using a data operation instruction. Copy the changed generation number from the data area to the generation number area again. Further, the data stored in the accumulator or the like is returned to the data area of the data packet.

The processing in this case will be described below using a specific example. In FIG. 20, the bit length of each field in the generation number is 4 bits, 10 bits, as shown in FIG.
When it is 10 bits, the pixel number PX is set to “2A
4 shows a flow graph of a program when "4" (hexadecimal) is added. In the following description, the numbers enclosed in "" generally represent hexadecimal numbers, and the numbers enclosed in quotation marks ("") generally represent binary numbers.

First, the flow graph of FIG. 20 will be described. Referring to FIG. 20, the numbers in the upper row in each node indicate the node numbers, and the letters in the lower row indicate the instructions executed at that node. The number (hexadecimal number) in the rectangle written on the right shoulder of each node indicates the right data for the instruction executed at that node.

Each instruction has the following meaning. "No
“P” is a one-input one-output instruction. In the case of the example shown in FIG. 20, it is used to copy an input data packet to create two data packets. The two data packets differ only in the destination number.

The "agn" instruction is a 2-input 1-output instruction. This command is a command for shifting the generation number of the left input to the right by the number of digits specified by the right data, and then writing it in the left operand area of the data packet.

The "add" instruction is a 2-input 1-output instruction. This instruction adds right data to left data.

The "and" instruction is a 2-input 1-output instruction. This instruction takes the logical product of left data and right data.

The "or" command is a 2-input 1-output command.
This instruction takes the logical sum of left data and right data.

The "sgnl" instruction is a 2-input 1-output instruction. This command uses the lower 12 bits of the left-hand generation number,
Set right data (contents of 2-input data area).

The operation of each node in FIG. 20 will be described below for each node. [Node 1] The node 1 uses nop to copy the data packet into two. The input data packet has a generation number and data as shown in FIG. In node 1, the right data "0" is used as a trigger. The generation numbers and data of the two data packets output from the node 1 are exactly the same as those of FIG. 21 as shown in FIG. These data packets are given to the nodes 2 and 3, respectively.

[Node 2] In node 2, the same processing as in node 1 is performed. As shown in FIG. 23, the generation numbers and data of the two data packets output from the node 2 are the same as those of the data packet of FIG. 21, and are given to the input of the node 4 and the left input of the node 9, respectively.

[Node 3] In the node 3, the lower 12 bits of the generation number are right-shifted by "0" bits (that is, right shift is not performed) by the agn instruction and moved to the data area of the data packet. Since the lower 12 bits of the generation number of the input of the node 3 are "9FF" as shown in FIG. 22, the output of the node 3 is the one in which "9FF" is set in the data area as shown in FIG. .

[Node 4] Node 4 also performs the same processing as node 3. The data packet output by the node 4 is shown in FIG.

[Node 5] In the node 5, "2A4" is added to the data area of the input data packet by the add instruction. Results are shown in FIG. This data packet is given to the node 7. The value of this data area is
This is a value obtained by adding "2A4" to the lower 12 bits of the generation number.

[Node 6] In the node 6, the contents of the data area of the data packet output from the node 4 and "C00"
Is ANDed with. Since the bit pattern of "C00" is "110000000000000", the contents of the output data area of the node 6 are "00" and the upper 2 bits of the 12-bit data in the data area of the input data packet. It will be connected. In the case of this example, the output of the node 6 is "800" as shown in FIG.
Becomes

[Node 7] In the node 7, the logical product is obtained between the value of the data area of the input data packet and "3FF". The bit pattern of “3FF” is “00
Since it is 11111111111 ", the value obtained by concatenating" 00 "and the value of the lower 10 bits of the value of the data area of the input data packet in the processing of the node 7 becomes the data area of the output data packet of the node 7. Is stored.

[Node 8] In the node 8, the logical sum of the right input data and the left input data is obtained. The lower 10 bits of the left input data are all "0", and the upper 2 bits of the right input data are "00". Therefore, by the process of node 8, a 12-bit value obtained by concatenating the upper 2 bits of the left input data and the lower 10 bits of the right input data is set in the data area of the output data packet. FIG. 29 shows the contents of the output data packet of the node 8 in this example.

[Node 9] In the node 9, the process of setting the contents of the right input data area to the lower 12 bits of the left input generation number area is performed. That is, the changed generation number stored in the data area is set in the lower 12 bits of the generation number area. Further, the contents of the original data saved in the accumulator or the like are set in the data area. The contents of the output of node 9 in this example are shown in FIG.
It shows in 0.

That is, by the processing shown in FIG. 20, the lower 12 bits of the generation number of the input data packet are set to "2A".
4 ”is added.

However, when the generation number operation instruction is not used as described above, it is necessary to take a great number of steps as described above even when the generation number is converted by a simple arithmetic operation. Therefore, there was a great difficulty in developing a program for conversion. In addition, it is very difficult to perform real-time processing on image data because it is necessary to execute a large number of steps. If general image data conversion, including image data enlargement, reduction, and rotation, is to be performed, it is extremely difficult and complicated to create the necessary algorithm without using generation number operation instructions. Since the amount of processing to execute is enormous, performing real-time processing is
Even in the case of uniform reduction, enlargement, and rotation processing, it is difficult.

(2) When a generation number calculation instruction is used The generation number calculation instruction is the operand data of the right input for any of the field number, line number and pixel number in the generation number of the input data packet. This is an instruction for performing an operation using the value of. As a result, the contents of the generation number are directly converted. It is not necessary to move the generation number to the data area, save the contents of the data area in advance, or restore the original after conversion.

An example of the generation number calculation instruction is "addpx".
It is an instruction. FIG. 31 shows a flow graph when the above process (1) (flow graph shown in FIG. 20) is performed using this instruction. The instruction “addpx” is an instruction to add the value of the right data to the pixel number in the generation number. However, in this case, the line number L after addition
It is assumed that there is no carry in the N area and there is no clipping for the addition result. The flow graph in this case becomes very simple as shown in FIG.

The conventional processing for rotating the image data using the generation number calculation instruction will be briefly described below.

Referring to FIG. 32, field number FD =
Consider a π / 4 rotational movement operation centered on the point A of pixel number = “1FF” and line number = “200” on the screen of “5”. The field number FD of the point B to be moved is “5”, the pixel number is px1, and the line number is ln1. The axes of coordinates px and ln are shown on the upper and left sides of FIG. 32, respectively. Further, the X-axis and the Y-axis are taken as shown on the lower side and the right side of FIG. px1 = x1,
"3FF" -ln1 = y1 is set. Similarly, the pixel number of the point C obtained by moving the point B by π / 4 rotation is px2 = x2, and the line number is ln2. Also, "3FF" -ln2 = y2
far. If point A is represented by the coordinate notation of (X, Y), (1F
F, 200). Further, as shown in FIG. 32, the angle formed by the line segment AB with the X-axis direction is α, and the length of the line segment AB is a.
And Then the following holds.

X2 = acos (α + π / 4) + 1FF ... y2 = asin (α + π / 4) +200 ... a = √ {(x1-1FF) ² + (y1-200) ² } Obtain the following expressions and.

X2 = a · (cosα−sinα) / √2 + 1FF ... y2 = a · (cosα + sinα) / √2 + 200 where cosα = (x1-1FF) / a, sinα =
From (y1-200) / a, the following equations and are obtained.

X2 = (x1-y1 + 1) / √2 + 1FF ... y2 = (x1 + y1-3FF) / √2 + 200 ... 3FF-ln1 = y1, px2 = x2, px1 described above
The following equation is obtained from the relationship of = x1.

Px2 = (px1 + ln1-3FE) / √
2 + 1FF ... Moreover, 3FF-ln2 = y2, px1 = x1, 3FF-
From the relation of ln1 = y1, the following equation is obtained.

Ln2 = (− px1 + ln1) / √2 + 1FF Equation and, from this, the flow graph of this processing is as shown in FIG. Of the instructions shown in FIG. 33,
The generation number calculation instruction that first appears in FIG. 33 is as follows. In the processing by the following instructions, it is assumed that neither carry, borrow bit, nor clipping is performed.

"Subpx" indicates that the right data is subtracted from the pixel number of the left data.

"Subln" indicates that the right data is subtracted from the line number of the left data. “Addln” indicates that the right data is added to the line number of the left data.

“Mulpx4” indicates a process of multiplying the pixel number of the left data by the right data and setting a value shifted to the right by 4 bits in the pixel area of the generation number. For example, in node 8, "B" (decimal "11") is given as right data. Therefore, by the processing of the node 8, the pixel number of the left data is multiplied by "11/16". This calculation is for approximating “÷ √2” that appears in the formula and.

"Mulln4" indicates that the line number of the left data is multiplied by the right data, and further shifted to the right by 4 bits and set in the line area of the generation number. For example, in node 9, “B” is used as the right data. Therefore, the line number "11/1
6 ”is multiplied. This instruction is also for approximating the process of dividing the line number by √2.

34 to 45 show generation numbers and data contents of data packets input to each node.
As shown in FIG. 34, the input data packet includes a generation number "5FFDFF" and data "9". The output data packet contains "5E7F9F" as the generation number and "9" as the data, as shown in FIG.

[0061]

When a generation number operation instruction is used and a generation number is converted by a simple arithmetic operation, a simple process as shown in FIG. 31 is required.
However, when general image data conversion processing as shown in FIGS. 32 and 33 is performed, the scale of the flow graph for that purpose becomes very large. Therefore, there is a problem that the processing takes time. Furthermore, as described above, “√
Divide by 2. For the processing "", refer to "11/1
There is no choice but to approximate by multiplying by a value such as "6. for that reason,
There is a problem with the accuracy of generation number conversion. The approximation accuracy can be improved by executing an instruction such as mulln4 many times, but there is a problem that the processing time increases accordingly.

On the other hand, the paper “Graphic data driven language UL1
"Mitsuo Akechi et al., The 32nd Information Processing Society of Japan (Showa 6
1st semester) National Convention Proceedings, pp. 209-210)
The "delay" command is introduced in. This instruction indicates “output of a token one generation behind the input token”, but in short, it is an instruction for adding 1 to the generation number. Using this instruction, for example, a process of directly adding a certain value to the generation number can be realized. For example, when adding 3 to the generation number, the delay instruction may be repeated 3 times. However, even if this instruction is used, it is impossible to realize an operation including subtraction, multiplication and division, and it is impossible to perform the rotational movement processing as described above. Further, when the configuration of the generation number is variable, such processing becomes more difficult.

The table memory 52 includes a data conversion table 70 and a generation number conversion table 72 similar to those shown in FIG. The contents of the generation number conversion table 72 will be described later with reference to FIG.

The merging unit 54, the firing control unit 56, the program storage unit 60, and the branching unit 62 are the same as those shown in FIG. Therefore, detailed description thereof is omitted here.

The VMS setting switch 64 is a manually operable switch, and in the case of the present embodiment, it is for giving a 2-bit generation number area allocation setting signal VMS to the arithmetic unit 58.

The details of the calculation unit 58 are shown in FIG. Referring to FIG. 2, operation unit 58 receives generation number GNT and right data RD in addition to data address generation unit 82, table access circuits 86 and 88, and multiplexer 90, and receives VMS signal and instruction information OPC. In response to the instruction number OPC, and a generation number address generation unit 80 or a data address generation unit 82 in response to the instruction information OPC.
A multiplexer 84 for selecting one of the outputs of the above and supplying it to the table access circuit 86;
In response to the NT, in response to the instruction information OPC and the VMS signal, the generation number extracting unit 92 for outputting only the content of the area specified by the VMS signal and the instruction information OPC in the generation number GNT, and the instruction information OPC. In response to

And a generation number setting unit 96 for rewriting and outputting a part specified by C by the output of the multiplexer 94.
The output of the generation number setting unit 96 becomes the generation number GNT output by the calculation unit 58. The output of the multiplexer 90 is the left operand data LD output from the arithmetic unit 58. Although not shown in FIG. 2, the instruction information OPC and the destination information are also transferred from the operation unit 58 to the program storage unit 60 (see FIG. 1).
Given).

The functions of the data address generator 82, the table access circuits 86 and 88, and the multiplexer 90 are the same as those of the conventional one shown in FIG. Therefore, details thereof are omitted here. The table access circuit 86 can access both the data conversion table 70 and the generation number conversion table 72 shown in FIG. Which to access depends on the address given from the multiplexer 84. Those addresses are generated by the generation number address generation unit 80 or the data address generation unit 82 as described above.

FIG. 3 shows a part of the contents of the generation number conversion table 72 shown in FIG. With reference to FIG. 3, in the generation number conversion table 72, at the address position generated from the generation number by a predetermined method, the contents of the converted generation number after performing the predetermined conversion on the generation number are stored in advance. Calculated and stored. However, in this case, the content of the converted generation number may be a part of the generation number such as a field number, a line number, or a pixel number, or the entire generation number.
The storage method differs depending on how the areas are allocated to the field number, the line number, and the pixel number in the generation number, and the contents of the conversion operation. In the case of the example shown in FIG. 3, the contents for realizing the process of simply adding “2A4” to the pixel number of the generation number are stored.

Generation number address generator 8 shown in FIG.
0 has the following functions. The generation number address generator 80 receives the input VMS signal and instruction information OPC.
4, the generation number area is divided into areas 100, 102 and 104 as shown in the upper part of FIG. 4, and a specific area 102 is taken out from the area and set as the lower address 108 of the generation number address. Is. In the case of the present embodiment, "0" is set to the upper address 106 of the addresses. For example, the areas 100, 102, and 104 may be field numbers of generation numbers, line numbers, and pixel numbers, or may be a part of them. The bit length of the address is specified by the instruction code. The generation number address generation unit 80 is AL
Have U.

FIG. 5 shows an example of how the generation number area is assigned to the field number, line number and pixel number according to the value of the VMS signal. When the value of VMS signal is 0, these are 4 bits, 10 bits,
A 10-bit area is allocated. When the VMS signal is 1, 3 bits, 10 bits and 11 bits are allocated respectively. When the VMS signal is 2, 2 bits, 11 bits, and 11 bits are allocated, respectively. When the VMS signal is 3, 0 bit, 12 bit, 12 respectively
Bits are allocated. Of course, what is shown in FIG. 5 is merely an example, and the generation number can be assigned by another method. In the case of this embodiment, 2 bits are assumed as the VMS signal, but it may be 1 bit or 3 bits or more.

The generation number extraction unit 92 first determines which of the four allocation methods shown in FIG. 5 is to be selected by the VMS signal. Further, the generation number extraction unit 92 determines, by the instruction information OPC, which part of which region is to be extracted from each of the regions allocated as shown in FIG. Give to input. Of course, the process of the generation number extraction unit 92 is
Since it is determined by the combination of the value of the VMS signal and the value of the instruction information OPC, it can be realized by a circuit basically having the same configuration as the data address generation unit 82.

The generation number setting unit 96 includes a generation number extraction unit 9
It can be considered that the operation roughly opposite to the operation 2 is performed. That is, the generation number setting unit 96 uses the generation number address generation unit 80.
Of the generation number GNT output by the VMS signal and the value of the area specified by the instruction information OPC are rewritten by the output of the multiplexer 94 and output. Multiplexer 9
The output of No. 4 is either the value extracted by the generation number extraction unit 92 or the output of the table access circuit 88, which is determined by the instruction code OPC.

Therefore, the functions of the generation number extracting section 92, the generation number setting section 96 and the multiplexer 94 are as follows. Referring to FIG. 6, the generation number extraction unit 92
Enter the generation number GNT in three areas 100 and 10.
It is divided into 2 and 104. This allocation is based on the VM as described above.
It is determined by the S signal and the command information OPC. The generation number setting unit 96 sets the values of the generation number areas 100 and 104 in the output areas 110 and 114 as they are. In addition, the multiplexer 94 uses the contents of the generation number area 102,
Which of the read data 120 read from the table is to be stored in the output generation number area 112 is determined by the instruction information O.
Select by PC. The data thus selected is set in the area 112 by the generation number setting unit 96, and the whole is output as the generation number GNT.

The operation of this embodiment will be described below by taking a pixel number conversion instruction called an rpx instruction as an example. This instruction rpx corresponds to the processing shown as the prior art in FIGS. 20 and 31. The data flow graph is shown in FIG. The rpx instruction is an instruction that sets the read value in the pixel number area of the output data packet by referring to the generation number conversion table with the pixel number as the lower address and the lower bits of the right data as the upper address. However, the left operand data of the left input is saved. In the case of this example, it is assumed that the px number 10 bits is the lower address and the lower 5 bits of the right data is the upper address (see FIG. 7).

FIG. 9 shows, as an example, the contents of the input packet, the contents of the processing performed by this data driven type information processing apparatus, and the contents of the output data packet. As shown in FIG. 9, as an example, the generation number “6A79F
It is assumed that a packet having "F" and "555" as data is input. First, the right data "2A" shown in FIG.
The lower 5 bits "00100" of "4" and the pixel area "0111111111" of the generation number are used to determine the address "1".
1FF ”is generated. This generation is performed by the generation number address generation unit 80 shown in FIG. Needless to say, the allocation of the generation number area at this time and which part is used for address generation are determined by the VMS signal and the instruction information OPC.

Referring to FIG. 2, the multiplexer 84 is
In response to the instruction information OPC being rpx, the output of the generation number address generator 80 is selected and given to the table access circuit 86. Therefore, corresponding data "0A3" (see FIG. 3) is read from address "11FF" of generation number conversion table 72 in table memory 52 by table access circuits 86 and 88, and given to multiplexers 90 and 94.

In response to the instruction information OPC being rpx, the multiplexer 94 responds to the table access circuit 8
The output of No. 8 is selected and given to the generation number setting unit 96. Therefore, as described above with reference to FIG. 6 regarding the functions of the generation number extraction unit 92, the generation number setting unit 96, and the multiplexer 94, the value of the generation number of the output packet is “6A78A3” as shown in FIG. On the other hand, the multiplexer 90 selects and outputs the output of the data address generation unit 82 in response to the instruction information OPC being rpx. Therefore, the data "555" of the input packet is output as it is. This is shown as the content of the output packet in FIG.

Generally, the multiplexer 84 selects the output of the generation number address generation unit 80 when the instruction information OPC is the generation number conversion instruction, and the output of the data address generation unit 82 when it is the data conversion instruction. Select.
The multiplexer 94 selects the output of the table access circuit 88 when the instruction information OPC is a generation number conversion instruction, and selects the output of the generation number extraction unit 92 otherwise. The multiplexer 90 uses the table access circuit 8 when the instruction information OPC is a data conversion instruction.
8 is selected, and in other cases, the output of the data address generator 82 is selected.

As described above, according to the data driven type information processing apparatus of this embodiment, the processing as shown in FIG. 20 can be realized by one instruction as shown in FIG. Therefore, there is an effect that the data conversion instruction can be executed much easier and faster than in the case where the conventional generation number operation instruction is not used. Further, since a complicated flow graph as shown in FIG. 20 is not required, there is an effect that the program can be easily developed.

In the above specific example, only the instruction rpx for converting the pixel number has been described, but similarly, for example, the instruction rln for converting the line number can be used. In this case, the line number area of the generation number area of the input packet is used to generate an address for accessing the generation number conversion table. That is, for example, the line number is set in the lower 10 bits of the address and the lower 5 bits of the right data are set in the upper 5 bits to generate an address for accessing the generation number conversion table.

In this case, the allocation of the generation number area is changed according to the value of the VMS signal as described above. It is assumed that this allocation is as shown in FIG. Then, for example, if the generation number of the input packet is "FFFFFF
If the right input data of the F ”and rln instructions is“ AAA ”, the generated address is“ 57FF ”when the value of the VMS signal is 2, and“ 2BFF ”when the value of the VMS signal is 0. V
When the value of the MS signal is 0 and the data read from the address "2BFF" is "000", "000" is written in the line number area (5th to 14th bits) of the generation number of the output data packet. 10 bits of "." Are set. That is, the generation number of the output data packet is "F003FF".

Similarly, when the value of the VMS signal is 2 and the read data is "000", the third generation number
The lower 11 bits of "000" are set from the bit to the 13th bit. Therefore, the generation number of the output data packet is "C007FF".

As described above, by using the data driven type information processing apparatus of this embodiment, generation number conversion processing can be easily performed. However, the effect of the data driven type information processing apparatus of the present invention is not limited to this. The data driven information processing apparatus of the present invention can perform general coordinate conversion operations such as image enlargement, reduction, rotation, etc. easily and at high speed, and far more accurately than conventional methods. Less than,
Such features of the data driven type information processing apparatus of the present invention will be described.

For example, for the rotational movement operation of a certain point on the image, the processing when the present invention is used will be described. For rotational movement operation, for example, rgnt instruction and rpl
Two instructions are prepared. A rotary movement operation can be realized by using either of them. In the following, first, the processing when using the rgnt instruction will be described, and then the processing when using the rlp instruction will be described.

(1) rgnt instruction The rgnt instruction refers to the generation number conversion table with the generation number (24-bit length) as the lower address and the right data as the upper address, and sets the read data as the generation number of the data packet. It is an instruction. A flow graph of the rgnt instruction is shown in FIG. In the example shown in FIG. 10, it is assumed that “8” is given as the right data.

FIG. 11 shows the contents of the generation number conversion table 72 for performing generation number conversion using this rgnt instruction. The generation number of the input data packet is "5.
FFDFF ”and the left data is“ 9 ”. The right data is "8" as described above. An address "85FFDFF" is generated from the right data and the generation number. By accessing the generation number conversion table 72 using "85FFDFF" as an address, the corresponding converted generation number "5D6759" is read. The read value is set to the generation number of the output data packet.

As the contents of the generation number conversion table 72,
If an address generated from each generation number and right data is subjected to a predetermined rotational movement operation for that generation number, the value of the generation number after the rotational movement operation will be set in advance. The rotation movement operation for the generation number can be realized with one command. The contents stored in the table are
For example, the value obtained by actually performing "division by 2" may be rounded to an integer and processed. Therefore, the accuracy is much higher than the conventional processing such as multiplication by "11/16". Further, by changing the value of the right data, the address for accessing the generation number conversion table can be changed. Therefore, a plurality of types of processing are realized by storing a plurality of types of tables in the generation number conversion table in advance and inputting a value designating any one of them as right data to the rgnt instruction. Can be done easily.

With the rgnt instruction, different coordinate conversion processing can be executed for each screen.

(2) rpl instruction The rpl instruction is almost the same as the rgnt instruction. The flow graph is shown in FIG. In the example shown in FIG. 12, “3” is given as the right input.

The rpl instruction refers to the generation number conversion table with the line number area and the pixel number area in the generation number as the lower address and the right data as the upper address, and the line number area and the pixel number area are read with the read value. Is an instruction to rewrite the value of. Also in this case, the allocation of the generation number area is set by the VMS signal.
In the example indicated by = 0, the line number area and the pixel number area have a total length of 20 bits.

It is assumed that the same data packet as that described in (1) is input. The values of the line number area and the pixel number area of the generation number are “FFDFF”. An address "3FFDFF" is generated from the right data "3" and the line number and the pixel number. By accessing the data conversion table 72 (see FIG. 13) using this as an address, the corresponding value “D675
9 ”is read. By setting the read value “D6759” in the line number area and the pixel number area,
The generation number of the output data packet is "5D6759".

By using the rpl instruction of (2), the same coordinate conversion process can be executed for the pixel at the same position on all fields.

12 and 13, the instruction code of the input packet is "rpl"("0B7"), the generation number is "5FFDFF", the left data is "9", the right data is "3", and VMS Let signal = 0.
Hereinafter, a packet calculation process in this case will be described. It should be noted that in the following description, the processing in each unit in the arithmetic unit of FIG. 2 will be sequentially described.

[Generation number address generation unit 80] In the generation number address generation unit 80, since the instruction information OPC is "0B7" representing the rpl instruction and the VMS signal is 0, the line number in the generation number area is set. Extract the area and pixel number area. That is, the lower 20 of the generation number area
Extract the bit "FFDFF". Further, the address "3FFDFF" is generated and supplied to the multiplexer 84 by using "3" of the right data as an upper bit and the above-mentioned "FFDFF" as a lower bit.

[Data Address Generation Unit 82] The data address generation unit 82 supplies 0 to the multiplexer 84 because the instruction information OPC is “0B7”.

Is "0B7", the output "3FFDFF" of the generation number address generator 80 is selected and given to the table access circuit 86.

[Table Access Circuits 86 and 88]
The table access circuits 86 and 88 allow the address "5FFD" of the data conversion table 72 shown in FIG.
"D6759" is read from "FF" and applied to multiplexers 90 and 94.

[Generation number extraction unit 92] Generation number extraction unit 9
No. 2 has the instruction information OPC of "0B7" and the VMS signal of 0. Therefore, "FFD" of the line number area and the pixel number area (lower 20 bits) in the generation number area
Only "FF" is extracted and given to the multiplexer 94. In the present description, the generation number address generation unit 80 and the generation number extraction unit 92 have the same area of the portion to be extracted from the generation number. It is also possible to extract a part.

[Multiplexer 94] Multiplexer 9
In response to the instruction information OPC being "0B7", No. 4 selects the output "D6759" of the table access circuit 88 and gives it to the generation number setting section 96.

[Generation number setting unit 96] Generation number setting unit 9
6, the generation number “5FFDFF” of the input packet output by the generation number address generation unit 80 and the output “D6759” of the multiplexer 94 are given. Since the instruction information OPC is “0B7” and the VMS signal is 0, the generation number setting unit 96 supplies the lower 20-bit area of the generation number “5FFDFF” of the input packet from the multiplexer 94 “D6759”. ],
Output. Therefore, the generation number of the output data packet is "5D6759".

As described above, according to the data driven type information processing apparatus of the embodiment of the present application, complicated image operations which are difficult to realize only by using simple arithmetic operations, such as enlargement, reduction, rotation processing, etc. With regard to, it is possible to easily develop a data flow program. Further, since such complicated processing can be processed by one instruction, image processing can be realized at high speed and sufficient real-time processing is possible. In particular, in a uniform image conversion process in which the reduction ratio is fixed or the rotation angle is fixed, such conversion operation can be realized with one command, so that the image processing can be performed more efficiently.
